Ten reasons to support renewable energy
| Date: 20/09/2011 |
Debate over the energy model can constantly be heard on the street: advantages and disadvantages of gas, coal and oil, the nuclear controversy, the viability of renewables… Among the torrents of arguments, here are 10 to that explain the vital role of clean energies within a sustainable economic model.
Renewables are not a project for the future or an
experiment - they are already a reality and production from them,
and their range, will steadily increase. According to the World
Wind Energy Association, world installed wind power capacity had
reached nearly 200,000 MW by the end of 2010, equivalent to 200
nuclear power stations and capable of producing 2.5% of the global
electricity demand. In Denmark, wind power already covers 21% of
electricity demand and in Spain and Portugal, 18%.
Renewables produce energy without releasing
greenhouse effect gases (GHG), making them an indispensable ally in
the fi ght against climate change. Governments are looking to
advance in this direction due to international commitments such as
the Kyoto Protocol, signed by 200 countries and which has the goal
of reducing emissions by 5% between 2008 and 2012 (on 1990 levels).
Supranational policies are also being applied, such as the
objective framed by the European Union: that this reduction reaches
20% in 2020. Recently, the European Commission said it would like
to reduce such emissions by between 80% and 95% by 2050 (compared
to 1990 levels).
This is why
they're known as renewables! Fossil fuels such as coal, oil and gas
do not replenish themselves, whereas sun, water and wind are
sources of energy that is always available.
Renewable energy
generation does not pose risks for people or the environment, which
is an advantage with respect to the doubts expressed over the
safety of nuclear energy or the concern for pollution associated
with fossil fuel use.
Water, wind and the
sun are energy sources that are available the world over. That
means that the capacity for generating enough and a variety of
renewables comes from indigenous supply base for any country.
As an indigenous resource, they eliminate the need to
import fossil fuels from countries rich in gas, and oil. The need
to import energy raw materials implies economic, and even
strategic, costs. High dependence on energy from abroad can produce
supply uncertainty due to political and economic problems in
supplier countries.
Disputes over the
control and ownership of raw materials, which exist in a small
number of countries, are one of the main causes of territorial and
geopolitical confl icts. Quite the opposite, renewable energies are
a distributed resource.
The cost of renewable energies is foreseeable and can
be planned for solely on the basis of the necessary investment to
exploit them - and not the cost of the raw material. Fossil fuels,
especially oil, are subject to large fl uctuations which result in
speculation in the markets and upset any planning.
Renewables are sources of wealth since they avoid
imports and, as such, external payments. Having a basic raw
material, such as energy, is a good basis for the competitiveness
of industry. By nature, renewable energies boost development in
rural areas, favoring a better territorial structuring of the
countryside, and can act as an industrial and technological motor
in the economy. At the end of the day, all this provides the
conditions for job creation.
Sun and wind are available without cost, although
investment and effi cient technological development has to be
carried out to make use of them as energy sources. The present
economic model is based on fossil fuels, with a cost structure that
penalizes its environmental effects and it is not transparent in
the payment of subsidies. Mature renewables technologies, such as
wind, would, in
fact, already be competitive or even cheaper if all of their
environmental costs were internalized.
Spain sets an example
Spain has been a pioneer in promoting renewable energies via the regulatory framework. This commitment has borne fruit, converting renewables into a real alternative for reducing energy dependence on other countries (although it is still over 80%) and creating export technologies and industries.
- Renewables in Spain in 2010:
- Met 32.6% of electricity demand.
- Avoided nearly 32 million metric tons of CO2 emissions.
- Avoided 4 billion euros of imports.
- Cut the trade defi cit by around 8.5%.
- Wind energy already meets the electricity needs of 10 million homes.
- The renewable energies sector has created nearly 100,000 jobs in Spain.
- Two Spanish companies are among the fi ve biggest wind power asset operators in the world, and three are among the fi ve largest in the solar thermal sector.
